Try this one. I took this code from a tutorial of the Spanish support forum of Forumotion. I have translated all the explanations but take into account that if you see some parts of the code in Spanish, it is for that and you don't have to worry about it because it will work regardless

I found the Slide Show Banner thread so I tried that one. It's exactly what I needed. It's so much easier for the banners to go in order for our forum because we update different banners according to what's airing on TV. This makes it easier to keep track of them all when I have to delete one link and replace it with an updated one, I have them numbered and named, so I know which is which.
